Description

Game Introduction

FNF: Bob’s B-Side Onslaught is a fan-made rhythm mod that brings a fresh wave of energy to the Friday Night Funkin' experience. This game features a collection of B-side songs—including Sunshine, Whitered, Run, Ron, Trouble, Onslaught, Little Man, Lennon, isherun, and Tackle—each with its own unique beat and difficulty. The core objective is to match arrow symbols that appear above Boyfriend's head by pressing the corresponding keys on your keyboard in time with the music. Developed by a talented team including ninjamuffin99, PhantomArcade 3K, Evilsk8r, and Kawai Sprite, with contributions from Deadstay, What_was_taken, SaadModOfs, and others, this open-source project encourages community support and creativity.

How to Play

To play, start by selecting either story mode or free play mode from the main menu. In story mode, you face Bob in a series of songs with increasing difficulty, while free play mode lets you practice any unlocked song. During gameplay, arrow symbols appear above Boyfriend's head. Press the matching arrow keys on your keyboard (up, down, left, right) in rhythm with the music. Each correct press builds your combo, but missing too many keys in a row will cause you to lose the round. Stay focused and keep a steady rhythm to defeat Bob.

Game Features

This game includes a variety of catchy B-side songs that add energy and variety to the classic FNF formula. Story mode offers a progressive challenge, while free play mode allows flexible practice. The arrow key challenges test your timing and reflexes, and the open-source community supports ongoing updates and creativity. The game is easy to pick up but hard to master, making it suitable for both casual players and rhythm game enthusiasts.

Tips for Success

Listen carefully to the beat of each song to anticipate the timing of arrow prompts. Practice regularly in free play mode to improve your reflexes and learn the patterns of each track. Try to maintain a steady rhythm and avoid rushing your key presses. Aim for an A-grade performance by building long combos and minimizing mistakes. Stay calm and focused, especially during faster songs, and remember that consistent practice is key to mastering the game.
